我正在尝试绑定一个可以动态更改为显示元素的自定义对象。
我的window.xaml现在有这个:
<StackPanel Height="310" HorizontalAlignment="Left" Margin="12,12,0,0" Name="Configuration_stackPanel" VerticalAlignment="Top" Width="264" Grid.Column="1">
<Label Content="{Binding Path=Client}" Height="22" HorizontalAlignment="Left" Margin="20,0,0,0" Name="Client" VerticalAlignment="Top" />
</StackPanel>
在window.xaml.cs中,我有
的成员public CustomObject B;
CustomObject有一个客户端成员。 B.Client,获取客户端名称(这是一个字符串)等
如何显示B.Client并在代码更改时更改它。
ie:如果在代码中我做B.Client =&#34; foo&#34;然后显示foo 如果我做B.Client =&#34; bar&#34;,则显示bar而不是foo。

您的CustomObject
课程必须实施INotifyPropertyChanged
界面:
public class CustomObject : INotifyPropertyChanged
{
private string _client;
public string Client
{
get { return _client; }
set
{
_client = value;
OnPropertyChanged("Client");
}
}
public event PropertyChangedEventHandler PropertyChanged;
protected virtual void OnPropertyChanged(string propertyName)
{
var handler = PropertyChanged;
if (handler != null)
handler(this, new PropertyChangedEventArgs(propertyName));
}
}
